evgeny	cc2d2b5f78	etcp: фикс UAF teardown (двойное закрытие линка) + вытеснение down-линка при коллизии адреса - tcp_link_close_cb (серверная ветка): убрать преждевременный огонь link_status/on_link_down, etcp_link_close сам снимает линк из списка и стреляет коллбэки в безопасном порядке (устраняет двойное закрытие линка — UAF из callring 45502) - etcp_connection_close: при callbacks_running откладывать закрытие через uasync_call_soon вместо (int)0=0 - callbacks_running: uint8_t-флаг -> int-счётчик вложенности (++/--) - etcp_fire_conn_status / etcp_fire_link_status_cbk: поднимать callbacks_running вокруг огня - insert_link_queue: при коллизии адреса с чужим conn — ERROR при одинаковом pubkey, отказ при up-линке, вытеснение (etcp_link_close) при down-линке Попутно: доки/комментарии в etcp_router, ACK-интервал 100мс->10мс (ROUTER_ACK_INTERVAL_TB).	5 days ago

Evgeny	58b9f28149	fix chatgui: prevent invite deadlock on connection flap cs_on_conn_down: remove invite state zeroing on disconnection. Only timeout callbacks and explicit protocol end (CS_MSG_ERROR, transition to JOIN phase) clear the invite state. Connection flap now causes automatic retry: conn_up → pending_invite_ch_id != 0 && !info_req_timer → resend CHANNEL_INFO_REQ. No deadlock possible.	3 months ago
Evgeny	f617dcd68e	db_sync: LMDB→SQLite, multi-instance, etcp_api, chatgui integration - src/db_sync: LMDB replaced with SQLite (separate tables per instance: db_sync_name_id) TTL index (author, timestamp), WAL mode, per-instance peers/timers opaque DB_SYNC_INSTANCE* handle, insert callback, select API new fields: author_signature, delivered_peers, delivery_chain transport: etcp_api direct P2P (was etcp_router) - src/db_sync.h: user-oriented API docs, multi-instance lifecycle - lib/Makefile.am: liblmdb sources removed - lib/sqlite3.c+h: SQLite amalgamation added - topo_node: LMDB→SQLite (src/topo_node_sqlite.c moved from chatgui) - chatgui: real db_sync.c replaces db_sync_stub.c chat_core: db_sync_insert_signed + dual-write insert callback utun_node: db_sync_init/destroy replaces chat_sync_init/destroy CMakeLists: stubs removed, real db_sync.c added	3 months ago

Evgeny	19a4505a03	chat_sync: новый протокол синхронизации чата вместо ChatPropagator - gui_bridge.h/cpp — кросс-поточные асинхронные коллбэки uasync↔GUI - chat_sync.h/c — протокол синхронизации (INIT_SYNC/RESP, SEND_DATA, PUSH/ACK, SYNC_DONE) - DbManager полностью переписан: per-channel таблицы msg_<ch> + peers_<ch>, 4 ключа в channels, signature, protocol/rtt в node_addresses, sync-методы - ChatPropagator удалён, заменён на chat_sync - db_sync_stub.c — заглушки для сборки chatgui без LMDB-версии db_sync - db_schema.md актуализирован под новую схему	3 months ago

Evgeny	2cd38988e6	AGENTS: add ASAN build instructions	3 months ago
Evgeny	53d41d5c62	fix: use-after-free in route table — add route_delete before u_free in route_bgp_update_my_nodeinfo and route_bgp_process_nodeinfo, relax routes_overlap to allow hierarchical routes Root cause: when bgp->local_node was reallocated (changed=1), old route entries remained with stale v_node_info pointing to freed memory. The freed memory got reused by a BGP peer's NODEINFO_Q, causing route_lookup to return wrong node_id (b3b2b1b0afaeadac instead of local), which then failed at etcp_route_send with 'no BGP route' and dropped packets to 10.23.2.1. Changes: - route_node.c: route_delete(old) before u_free + route_insert(new) after alloc - utun_instance.c: remove duplicate route_insert (now atomic inside function) - route_bgp.c: route_delete before freeing old peer NODEINFO_Q - route_lib.c: routes_overlap now rejects only exact prefix+network duplicates - tests/Makefile.am: add route_lib.o to test_route6_lib	3 months ago
